At Tim Kyle Electric, Heating & Cooling, we believe that honesty, respect, and integrity are important. That’s why we have up-front pricing. You approve the price before we start your job. We also respect your home. All of our employees have to pass drug tests and background checks before they begin employment with us. All of our electricians are professionally trained and uniformed service technicians.

"Rob was great from the estimate visit, to estimate delivery, and in coordinating the installation appointment (had to sub-contract in a roofer). On the day of service, Rob and Austin arrived on time (as did the roofers) and made quick work of the installation. It seems a rarity to find truly knowledgeable and friendly contractors that are both prompt and excellent communicators. This experience shined on all fronts. Will definitely be using Tim Kyle again. Appreciate the work Rob/Austin!"

Holtzople is a leading HVAC company in Frederick, Carroll, and Washington counties in Maryland, as well as Adams and small parts of Franklin & York counties in Pennsylvania, featuring all the top brands in the Heating and Cooling industry, such as Trane, Bryant, Lennox, Carrier, ClimateMaster, WaterFurnace, and more. We recently added an electrical department to our services, making us your one-stop shop for HVAC and electrical needs. Quality is Not Expensive, It's Priceless!

"Ok, some neighbors complaint how expensive Holtzople can be, but boy, you don’t get such quality and service elsewhere. We have had them for decades and this year needed a new unit because ours was so old, and this latest model was installed in three days, right before that June heat wave hit. And you get two free inspections following installation to see that it is working optimally with the most incredible work force ever—on time, competent, polite, caring and oh so concerned that you are a satisfied customer. For our money, they don’t come any better! And you’d be amazed at the nos. of people who agree with us!"

FAQs for thermostat installation and replacement projects in Westminster, MD

Smart thermostats may be worth it for many homeowners. They come with various features, including voice control and smartphone apps. Vacation mode can help lower energy usage when you’re out of town for an extended period. Alert warnings let you know about major spikes or drops in temperature. Smartphone apps can track energy usage, and smart thermostats can learn your routine over time to adjust your temperature and reduce wasted energy consumption automatically.

You typically do not need more than one smart thermostat. While it’s common to see multiple mechanical thermostats throughout a large home, multiple smart thermostats may try to override each other. This can lead to problems with the HVAC system. Ensure the unit you buy has the option for dual- or multi-zoned systems to avoid compatibility issues.

Installing a programmable or smart thermostat may save you $180 per year in utility costs. A big part of this comes from a smart thermostat’s ability to learn and adapt to your regular routines. With smartphone apps or web-based interfaces, you also have the option to control your thermostat when you’re not home.
